Answer 1

Ans: ATP producing reactions in glycolysis;

Reaction I : Transfer of phosphoryl from 1,3-bisphosphoglycerate to ADP.

O o-po HCOH CH,OPOZ Rib Adenine 1,3-Bisphosphoglycerate ADP Mg2+ phosphoglycerate kinase 0-P=0 oo HCOH CH,OPOS Rib Adenine 3-Phosphoglycerate ATP AG' = -18.5 kJ/mol

Reaction II : The last step in glycolysis is the transfer of the phosphoryl group from phosphoenolpyeuvate to ADP:

00 C-0-P-0- + P CH 0 Rib Adenine Phosphoenolpyruvate ADP Mg2+, K+ pyruvate kinase -0–P=0 C=0 + CH3 Pyruvate Rib Adenine ATP AG' = -31.4 kJ/mol
